Sry I didn’t notice this thread earlier.
TTL input can go with 0 -24V. Any voltage higher than 2,5V will result in max power.
ANG input should be used with maximum 5V. And current flowing through the diode is proportional to this input.
You can use 2kohm resistor in series to the analog input and then it can also be connected to 10V. When you connect 10V to the ANG input without the resistor it will work linearly in 0-5V range and in 5-10V it will be outputing max power but will not damage the unit because of too high coltage.
1kHz PWM will also work while connected to the PWM output. Grayscale may work a little worse then but it depands also on fall/rise time of the impulse. Using higher PWM frequency you make sure that power is averaged properly. But for 1kHz PWM even the DAC are not perfectly working because the response time is 1ms. The difference can be seen with high feed rate when during this 1ms time laser is changing the position. Anyway 1khz means 1000 samples per second, while engraving the feedrate is around 30mm/s it means that every 0,03mm the material is receiven the laser shot. It is very short time and only some of the materials can show the difference.
Here is the drawing for connection. (Sry for the form, we will prepare something done better way for the instruction). New docking station will have all inputs/outputs as 1 to 1 without the order change.
